Context7 Auto Research fetches the latest library and framework documentation for Claude Code via the Context7 API, keeping answers current when asking about React, Next.js, Prisma, or other popular stacks.

This skill provides patterns for implementing robust data quality checks, utilizing industry standards like Great Expectations and dbt tests, and formalizing data contracts. It is essential when building reliable data pipelines, establishing validation rules, monitoring data quality metrics, or automating data validation within CI/CD environments.

Blueprint for designing comprehensive test suites, guiding when to add unit, integration, or E2E tests, selecting frameworks, managing data/mocks, and validating coverage and reliability.

Guides development of Django 5 apps and DRF APIs by defining indexed models, serializers, viewsets, authentication, and optimized ORM queries, plus enforcing permissions and tests before deployment.

Expert .NET backend architect guidance for C#, ASP.NET Core, Entity Framework, Dapper, caching, testing, and DevOps so teams can build production-grade APIs, microservices, and enterprise applications with clear patterns and performance best practices.

This skill acts as an expert dependency management consultant, specializing in planning and executing safe, incremental upgrades for project dependencies. It provides comprehensive risk assessment, compatibility reports, detailed migration guides, and robust testing/rollback strategies to ensure system stability while keeping dependencies current and secure. Ideal for complex software maintenance and modernization workflows.

Automatically produce mocks, stubs, spies, or fakes for unit tests by analyzing dependencies and using frameworks like Jest or Sinon, so you can isolate modules quickly without hand-writing boilerplate doubles.
